“This year is my seventh show, so seven years I’ve been doing it, it’s outrageous,” the supermodel shares. “I still can’t believe it’s been seven years. I started with Pink and then upgraded to the big girl section,” she adds laughing.

As for what Behati sees in him, she jokes: “I ask myself that everyday.” The duo surprised everyone with their engagement back in July after making if official after a short break. “I think he figured that one out. He needed time to realize that,” Behati says about why she thinks they broke up and then got back together only to get engaged soon after.

“But he’s awesome and we’re very happy and we just get each other and I think we realized that after a while.” Not to mention, she adds, “He’s the Sexiest Man Alive!”

So what’s their plan for the big day? For one thing, Behati admits: “[Well] we’re not having two weddings, I can just tell you that, that was a rumor that started from I don’t know who.”

Tune in tonight to see Behati and the other Angels walk in The Victoria’s Secret Fashion Show on CBS at 10/9c.
